Fuzzy text (sentences/titles) matching in C#
Hey, I'm using Levenshteins algorithm to get distance between source and target string. also I have method which returns value from 0 to 1: /// <summary> /// Gets the similarity between two strings. /// All relation scores are in the [0, 1] range, /// which means that if the score gets a maximum value (equal to 1) /// then the two st...
How do I tokenize a string in C++?

Best way to parse Space Separated Text
I have string like this /c SomeText\MoreText "Some Text\More Text\Lol" SomeText I want to tokenize it, however I can't just split on the spaces. I've come up with somewhat ugly parser that works, but I'm wondering if anyone has a more elegant design. This is in C# btw. EDIT: My ugly version, while ugly, is O(N) and may actually be ...

What is the best way to convert between char* and System::String in C++/CLI
What is the approved way to convert from char* to System::string and back in C++/CLI? I found a few references to marshal_to<> templated functions on Google, but it appears that this feature never made the cut for Visual Studio 2005 (and isn't in Visual Studio 2008 either, AFAIK). I have also seen some code on Stan Lippman's blog, but it...
How can I replace newline characters using JSP and JSTL?
I have a list of bean objects passed into my JSP page, and one of them is a comment field. This field may contain newlines, and I want to replace them with semicolons using JSTL, so that the field can be displayed in a text input. I have found one solution, but it's not very elegant. I'll post below as a possibility. ...
Algorithm for joining e.g. an array of strings
I have wondered for some time, what a nice, clean solution for joining an array of strings might look like. Example: I have ["Alpha, "Beta", "Gamma"] and want to join the strings into one, separated by commas – "Alpha, Beta, Gamma". Now I know that most programming languages offer some kind of join method for this. I just wonder how the...
How to get rid of `deprecated conversion from string constant to ‘char*’` warnings in GCC?
So I'm working on an exceedingly large codebase, and recently upgraded to gcc 4.3, which now triggers this warning: warning: deprecated conversion from string constant to ‘char*’ Obviously, the correct way to fix this is to find every declaration like char *s = "constant string"; or function call like void foo(char *s); foo...
C# Casting vs. Parse
This may seem rudimentary to some, but this question has been nagging at me and as I write some code, I figured I would ask. Which of the following is better code in c# and why? ((DateTime)g[0]["MyUntypedDateField"]).ToShortDateString() or DateTime.Parse(g[0]["MyUntypedDateField"].ToString()).ToShortDateString() Ultimately, is it ...
Ignore case in Python strings
What is the easiest way to compare strings in Python, ignoring case? Of course one can do (str1.lower() <= str2.lower()), etc., but this created two additional temporary strings (with the obvious alloc/g-c overheads). I guess I'm looking for an equivalent to C's stricmp(). [Some more context requested, so I'll demonstrate with a trivi...
What's the best way to build a string of delimited items in Java?
While working in a Java app, I recently was needing to assemble a comma-delimited list of values to pass to another web service without knowing how many elements there would be in advance. The best I could come up with off the top of my head was something like this: public String appendWithDelimiter( String original, String addition, St...

Simple haskell string manage
Theres is a little problem I want to solve with Haskell: let substitute a function that change all of the wildcards in a string for one concrete parameter. The function has de signature of: subs :: String -> String -> String -> String -- example: -- subs 'x' "x^3 + x + sin(x)" "6.2" will generate -- "6.2^3 + 6.2 + sin(6.2)" ...
Comparing names
Is there any 'simple' algorithm to determine the likeliness of 2 names representing the same person? I'm not asking for something of the level that Custom department might be using. Just a simple algo that would tell me if 'James T. Clark' is most likely the same name as 'J. Thomas Clark' or 'James Clerk'. If there is an algo in C# that...
Algorithm for finding characters in the same positions in a list of strings?
Suppose I have: Toby Tiny Tory Tily Is there an algorithm that can easily create a list of common characters in the same positions in all these strings? (in this case the common characters are 'T' at position 0 and 'y' at position 3) I tried looking at some of the algorithms used for DNA sequence matching but it seems most of them ...
Does C# have a String Tokenizer like Java's?
